John Whittington stands on the platform of one of several tankcars purchased for biodiesel storage at Integrity Biofuels, a Grammer Industries subsidiary. The Integrity Biofuels location in Morristown IN is one of two facilities the carrier has upgraded to include transloading services.

Grammer Industries' initial foray into storage tank operations started in 2001 with the purchase of the Van Wert OH facility. The seven-million-gallon tank was already being used to store anhydrous ammonia.

A subsidiary of Grammer Industries, Integrity Biofuels has a capacity to produce 10 million gallons of biodiesel a year from soybean oil. The Morristown IN transload facility operates under the Integrity Biofuels name and shares space and resources with the plant.

Grammer Industries runs one of the largest MC331 fleets in the trucking industry, and uses them to haul anhydrous ammonia and propane. Also part of the fleet are MC312 and DOT412 trailers that are used for nitric acid and other corrosive cargoes.
